IMPROVEMENT lN SPRINGS FOR VEHICLES.

Specification forming part of Letters Patent No. 165,641, dated July 13,1875; application filed December 30, 1874.

To all whom "it may concern:

Be it known that I, WILLIAM F. WHITNEY, of New Paltz, in the county ofUlster and State of New York, have invented certain Improvements inSprings for Vehicles; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being bad to theaccompanying" drawing forming part of this specification.

My invention relates to certain improvements in springs operating on thetorsion principle; and it consists in the combination, with the frontaxle and bolster, having its ends curved forward, of arms having eyes attheir lower ends for the reception of the curved ends of the bolster,the uppeuend of said arms being attached to the ends of the torsionalspring-bars, all of which will be fully hereinafter described, andpointed out in the claim.

In the accompanying drawing, Figure 1 is a side sectional view ofacarriage with my improvement applied thereto. Fig. 2 is a bottom viewof the same. Fig. 3 is a front View of the same. Fig. 4. is a detailView.

A represents the body of a carriage of any ordinaryconstruction. B is ametallic bracket, at the ends of which are perforated lugs b b, forsecuring it to the under side of the bottom of the carriage-body A.About midway of the length of the bracket are two holes, one of which isround, and the other square. The square hole 0 is for the reception of asquare tenon on one end of a rod, E, and the round hole (I is for thereception of the round portion of a similar rod. Four of these bracketsare attached to the under side of the bottom of the body A, near thefour corners thereof, with the length of the bracket parallel with thelength of the body. The rods E are made of elastic steel, and serve assprings by operating on the torsion principle. They are applied to thebrackets by inserting the square tenon in the square hole 0 of onebracket, while the rounded portion of the rod, near the opposite end,passes through and works freely in the round hole d in the oppositebracket,

projecting slightly beyond the same. Two of the rods are applied to thebrackets at the rear end of the body, and two more to those at the frontend. The rods are so arranged that the square tenon of one rod engageswith the square socket in the bracket on one side and downward from thebody A. The arms G at the rear end of the body, are attached directly tothe rear axle J by means of clips g, formed on their lower ends. Thearms G at the front end, are attached to a bolster-rod, H, the ends ofwhich are round, and engage with eyes 7L, formed at the lower ends ofthe arms. The front axle K is attached to the bolster-rod H by means ofa king-bolt, i; and in order that said axle may retain its properposition directly under the bolster-rod, and not be pulled forward, soas to bend the king-bolt, the ends of the bolster-rod are bent or curvedforward, so that the axle K will occupy a posit-ion somewhat to the rearof a line drawn through the eyes It at the lower ends of the arm. Thethills L are rigidly attached to the front axle, and the necessaryoscillation thereof, resulting from the motion of the horse, ispermitted by the free working of the ends of the bolster-rod in the eyesh.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of the front axle K, the bolster H, havingits endscurved'forward, and the arms G having eyes It at their lower ends forthe reception of the curved ends of the bolster, substantially as shownand described.
